Thank you. I had somehow overlooked that post, and it's useful information. Because the student has obtained a recommendation -- although not from Dini -- it appears that he is unharmed. He can go on to a career in "creation science" if he likes, and live happily ever after. Because he is now (or should be) a happy camper, I don't know why he is pushing what seems to be a religiously-motivated vendetta (or is it a witch-hunt?) against Dini; and I don't think the DOJ should be harrassing Dini for his scientific beliefs. It smacks too much of the Galileo affair.
That's a good question.
There's another strange thing about this student that has me wondering about his motivation. He was unwilling to provide a scientific understanding of human origins in to Dini in person, but was intent, at first, on getting an A in the class. As this was an introductory biology class, he would have had to affirm, in writing, evolutionary theory on the tests. What's the difference?
Indeed, the fact that he was able to obtain a letter from another school limits his damage claim to costs of transfer, time lost, mental anguish. But that's if he files a lawsuit personally.
My guess is that the lawfirm sees this as a landmark case (witch hunt as you called it) - to enforce the anti-discrimination laws.
